Description of the Related Art In general, a steam generator of this type, which evaporates water by boiling to generate steam, is a steam generator provided in a can body 15 and a space above the can body 15, as shown in FIGS. An outlet 18 and a water supply port 17 provided in the lower water of the can body 15 are provided. The fins 16 welded to the outer surface of the can body 17 are
The water 22 inside the can body 15 is heated to boil and evaporate to generate steam 23, and the steam 23 is taken out from the steam outlet 18. By continuing this state, the water 23 in the can 15 is reduced because the steam 23 is taken out to the outside, but the electrode provided in the can 15 has a straight rod-shaped upper water level sensor 19, The water supply sensor is controlled by the water level sensor 20, and the water level is always kept within the range where both water level sensors are located. Further, since the steam 23 is continuously generated, water is supplied from the water supply port 17, but scale components (calcium, magnesium, silica, etc.) contained in the water are concentrated and adhered to the water level sensors 19 and 20. . Details are shown in FIG. It is composed of an insulator 24 and a linear rod-shaped electrode 25, and the attached scale 26 becomes an insulating object, which makes it impossible to energize and no longer detects the water level. Therefore, in order to prevent the scale from adhering, the water to be replenished is supplied to the water supply pipe 27.
A structure was used in which calcium, magnesium, etc. were removed by the water softener 21 connected to the.

The water level sensor used as above shows that the electrode contracts at high temperature. FIG. 2 shows a state in which the electrodes are expanded by cooling after the steam generator is stopped. In FIGS. 3 and 4, a burner 4 as a heating means is arranged below the can body 5 with a constant combustion space. The can body 5 is provided with a steam outlet 8 in the upper space and a water supply port 7 in the lower water, and a large number of fins 6 that absorb the combustion heat of the burner 4 are welded to the outer surface of the can body 5. Further, inside the can body 5, a high water level sensor 9 for high level detection and a low water level sensor 10 for low level detection are provided.
